UNITED STATES HELEN O. LARSON, OF LOS ANGELES, CALIFORNIA.

COOKER.

Application filed July v2,

To all 207mm it may concern.'

Be it known that I, HELE-N O. LARsoN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Cookers, of' which the following is a specilicationf My object is to make an improved cooker, and my invention consists of the novel featu-res herein shown, described and claimed.

Figure 1 is a diametrical sectionalelevation of a cooker embodying the principles of my invention, the view being taken substantially on the lines 1*1 of Figs. 2 and 3.

the line 2 2 of Fig. 1 and, looking downwardly as indicated Vby the arrows.

Fig. 3 is a horizontal sectional detail on the line 3 3 of Fig. 1 and lookingdownwardly as indicated by the arrows.

The fiat bottom 1 is made of heavy sheet metal and is adapted to rest upon a stove top or grate for heating. The annular wall 2 is connected to the edge of the bottom 1 all the way around by a seam 3. The upper edge 4 of the annular wall 2 is wired and a door opening 5 is formed through the annular wall 2 below the wired edge 4 and eX- tending substantially half way around Vand half way down. Sliding doors 6 and 7 are mounted in position to open and close the opening 5. The doors 6 and 7 tit against the outer face of the wall 2 and are vheld in place by guide rails 8 and 9, said guide rails extending all the way around so that the doors may be moved apart to completely clear the opening 5. The ledge 10 is inserted inside of the wall 2 to lorm the bottom of the door opening 5, and a similar ledge 11 is inserted to form the top of the Y door opening 5.

V Asbestos illing 12 is placed inside of the annular wall V2 all the way around. An angle iron flange 13 is secured to the bottom 1. The annular' lining wall 14 is secured to the flange 13 and fits vinside 'of the asbestos filler 12 parallel with the wall 2 and evenly spaced therefrom all the yway around.

A ledge 15 extends from the upper edge. of the lining 14 over the top of the filler 12 andis bent around the wired edge 4 to hold the lining securely in place. The lining l14 and the bottom 1 are adapted to hold water 16 up to the ledge 10. A water glass 17 is mounted at the opposite side of the wall 2 from the opening 5 and-has connections 18 Fig. 2 is a horizontal sectional detail on Speccaton of Letters Patent.

and 19, the connection 18 extending into the air chamber 2O above the water, and the connection 19 extending into the lower part of the water 167 the object of the water glass being to show the level of the top of the water 16.

A stand is mounted upon the bottom 1 and .comprises the flat plate 21 and legs 22. The cooking receptacle 23 rests upon the stand plate 21 and has handles 24 for inanipulating the receptacle. The receptacle 23 is circular in plan and considerably smaller than the lining wall 14, so that the receptacle may be submerged in the center of the water 16 tothe desired depth, and so that the water will circulate equally all the way around. The space around the receptacle is substantially equal in thickness to the space below the receptacle. A flat cover 25 lits upon the receptacle 23 and lhas a flange 26 fitting insiderofthe cover. i i

The cover 25 has perforated portions 27 and 28 and imperforate portions 29 andv 30. The perforated or foraminous portions 27 and 28 are arranged diametrica-lly opposite each other and the imperforate portions 29 and 30 are diametrically opposite each other and at right angles to the oraminous portions. Triangular dampers 31 and 32 are connected to the cover 25 by loose rivets 33 and 34, so that the dampers will swing on to the imperitorate portions 29 and 30 and open the foraminous` portions, and so that the dainpers will swing over the foraininous portions 27 and 28 and close the circulation through the cover. The cover 25 is. held removably in place upon the receptacle 23 by snap hooks 35. and 36 hingedly connected to the receptacle and adapted to engage the cover.

A curved .angle iron flange 37 lits against the inner face oli' the annular lining wall 14 `on a level with the ledge 10. and the shelf 38 is adapted to slide through the door opening 5 and rest upon the flange The shell 38 has a series of openings 39 evenly spaced apart and .extending all the way around just inside of the Harige 37. rl`he triangular cooking receptacles 40, 41 and 42 are adapted to pass through the door opening 5 and slide on to the shelf 38.

The cooking receptacles 40, 41 and 42 are substantially alike, and each has a curved outer wall 43 and flat straight inner walls 44 and 45, the walls 44 and'45 being substantially radial to the center of the shelf,

and the receptacles being small enough, so that when in place there are passages 46, 47 and 48 betwen the fiat sides of the receptacles and a passage 49 all the way around the receptacles so as to allow vthe steam and heat to circulate freely.

The tops of the receptacles 40, 4l and 42 each have foraminous portions 50 adapted to be covered and uncovered by dampers 5l secured in place by loose rivets 52. rlhe covers 53 of the receptacles are removably mounted and held in place by the snap catches 54, and each receptacle is provided with a handle 55 projecting outwardly from the curved side.

The conical steam collecting cover 56 has a'flange 57 adapted to rest upan the ledge l5 and extend downwardly inside of the upper part of the annular lining wall l14 so as to make a close joint. A filling funnel 58 is mounted to extend through the cover 56 and has a spout 59 extending below the cover and discharging downwardly into the space 60 outside of the cooking receptacles and just inside of the annular lining'wall 14, so

. that water may be poured into the funnel to raise the level 61'of the water 16 to the desired point. A cap 62 isadapted to close the funnel steam tight and the cap 62 is connected to the funnel 58 by a chain 63. The funnel 58 has a wired upper edge 64 and the cap 62 fits tightly in the funnel like W a cork. A

The cover 56 has a central outlet 65, a

frame 66 is mounted in the cover below the outlet 65, and a wind wheel 67 is connected to the frame 66 by a spindle 68, so that the wind wheel will be operated by steam'and air passing upwardly through the outlet 65. A pipe 69 is connected to the cover 56 around the opening by a nipple 70. An asbestos filler 71 is placed upon the cover 56 and a second cover 7 2 is placed upon the asbestos filler 71, said second coverriitting around the pipe 69 and fitting around the outer edge of the cover 56 so as to hold the asbestos 71 in place. A stop valve 7 3 is incorporatcdinto the pipe 69, an elbow 74 is connected to the valve 7 3, an enlarging nipple 75 isconnected to the elbow 74, a large pipe 76 is connected to the nipple 75, and a damper 77 is mounted in the pipe 76. The

pipe 76 is adapted to be connected to a chimney flue or stove pipe.

The cooker thus constructed is adapted to be' heated by placing overa gas lire or in anyvother suitableway to heat and boil theV water 16, Vand the steam will circulate around the cooking receptacles and into the tops of the cooking receptacles, and the regulating valve 73 may be opened to any desired extent until the steam becomes hot, then the valve 7 3 may be closed and the fire shut off and the cooker will operate like a tireless cooker.

The admission of steam to the tops of the receptacles may be closed or regulated by manipulating the dampers 31, 32, and 5l, and the outlet of steam from the cooking chamber may be regulated by the damper 7 7 @ther advantages and uses are obvious, for instance, the cooker may be operated purely as a Yiireless cooker and without a stove by supplying hotl water through the funnel 58 Y Y lNhen the cooker is to be used on top of a gas burner or on top of a stove the heat will be applied directly to the bottom l, and

the water 16 rests directly on this bottom l so that the water will readily heat and the heat insulated walls will retain the heat and if desired, after the cooker hasbeen well heated, it may be raised and an yinsulating pad placed under the bottom to `assist in holding the heat. Y -Various changes may Abemade without departing from the spirit of my invention as claimed.

I claim Y Y In a cooking utensil, a vessel provided in its side wall with an opening, the lower edge of which occupies a horizontal plane a substantial distance above the bottom of the vessel, whereby a considerable volume of water may be maintained in the lower portion of the vessel, doors for closing said opening, a supporting frame positioned on the bottom of the vessel, a cooking receptacle removably positioned in the lower portion l ing receptacles removably positioned on said partition, perforated covers for said receptacles, dampers pivotally mounted on said covers and adapted to close the perforations therein, acover for the vessel, which`c`over Y is provided with a steam outlet and a funnel Y having a spoutrthat extendsthrough the cover and downwardly into the upper portion of the chamber within theV vessel.

In testimony whereof I havevsigned my name to this specification.
